02359 - General Pathology and Physiopathology

Learning outcomes

At the end of the course the student: - has clear concepts of disease, etiology and pathogenesis, also knows the etiology of morbid processes and understands the pathogenetic mechanism of their development; - knows the fundamental biological defenses implemented in response to pathogens, the morphological alterations that the latter cause in cells and tissues and the systemic and functional consequences for the organism; - is capable of connecting molecular, morphological, microbiological, immunological and physiological knowledge with the etiopathogenesis of the disease processes and the fundamental pathophysiological mechanisms of the organism; - will be able to use basic biomedical knowledge and general pathology and pathophysiology for the critical interpretation of experimental and clinical data; - is able to understand the reasons for the signs and symptoms of morbid processes and has the basis for a clinical practice based on objective findings.
